Maybe I hav'nt explained myself too well so I will try to do so now? I agree to some extent that hairbrushes can tickle, its very rare but all the same, I understand where you are coming from. If you look closely at the vids where feet are tickled with the hairbrush, they are not tickling gently as you should, but they really go to town with them and scrub the feet as hard as they can. Is this just to get a reaction from someone, who knows? If you look closely at the models faces, you can see that they reacting in a certain way to make the vid entertaining. If something tickles I'm all for it but it has to tickle, not hurt.
